/*
Parse user value to user name and host name parts .
SYNOPSIS
user_id_str [ IN ] User value string ( the source ) .
user_id_len [ IN ] Length of the user value .
user_name_str [ OUT ] Buffer to store user name part .
Must be not less than USERNAME_LENGTH + 1 .
user_name_len [ OUT ] A place to store length of the user name part .
host_name_str [ OUT ] Buffer to store host name part .
Must be not less than HOSTNAME_LENGTH + 1 .
host_name_len [ OUT ] A place to store length of the host name part .
RETURN
0 - if only a user was set , no ' @ ' was found
1 - if both user and host were set
